Djed
Stablecoin Cardano’s Verified Algorithmic Solution
Djed is an advanced algorithmic stablecoin developed by Input Output Global (IOG) and powered by COTI. Designed to function like an autonomous bank, Djed maintains its value through a system that buys and sells stablecoins within a specific price range. It is backed by ADA, Cardano’s native cryptocurrency, and supported by SHEN reserve coins to ensure stability.
Client Requirements
The primary requirement for the Djed stablecoin was to establish a reliable system that maintains price stability in volatile markets. This involved creating a protocol that effectively manages the value of the stablecoin through an autonomous mechanism. The client needed the protocol to be crypto-backed, specifically utilizing ADA as the main collateral and SHEN as a reserve coin. This setup aimed to ensure that the stablecoin’s value remains consistently pegged within a specified range. The protocol’s design had to incorporate an over-collateralization strategy with a reserve ratio between 400% and 800% to absorb market fluctuations and safeguard the coin’s value.
Additionally, formal verification of the stability claims was crucial. The client required that the stability mechanisms be rigorously proven through mathematical proofs to build trust and ensure the protocol’s integrity. This involved using advanced techniques like bounded model checking and interactive theorem proving to exhaustively validate the system’s stability. The overall goal was to deliver a stablecoin with transparent, reliable, and mathematically verified mechanisms that could provide users with consistent value and security in the ever-changing crypto market.
Features
Djed Stablecoin Cardano’s
Transparency
Djed ensures real-time transparency, providing users with current data on prices, supply, and reserves, building trust and confidence by allowing verification of the stablecoin’s backing and overall stability.
Mint and Burn Mechanism
Djed uses mint and burn to control supply, maintaining its peg by creating or destroying coins as needed to stabilize the price and ensure consistent value in the market.
Crypto-Backed
Djed is backed by ADA and SHEN, combining robust collateral assets to maintain its peg and absorb market volatility, ensuring reliability and trust within the crypto ecosystem.
Over-Collateralization
Djed maintains a 400–800% reserve ratio, ensuring excess collateral value to protect against volatility and uphold price stability, making it a secure and stable digital asset.
Formal Verification
Djed uses formal methods like model checking and theorem proving to validate its mechanisms, ensuring mathematical accuracy, reliability, and building user confidence in the protocol’s operation.
Dynamic Pricing
Djed adjusts buy and sell prices based on market behavior, automatically managing supply and demand to maintain its peg and keep value stable across changing conditions.
Algorithmic Stability
Djed uses algorithms to autonomously balance supply and demand within a price range, maintaining peg stability like a digital bank that reacts to market conditions instantly.
Reserve Coin (SHEN)
SHEN acts as a reserve coin, absorbing volatility and supporting Djed’s peg stability, rewarding holders while maintaining collateralization and safeguarding the stablecoin’s consistent value.

Consensus Mechanism
Automated Price Adjustment
Djed uses automated algorithms to adjust buy and sell prices in real-time, stabilizing its value by responding instantly to market changes and maintaining the peg within a specific range.
Dynamic Reserve Adjustments
Djed dynamically adjusts reserve levels and collateral ratios based on market conditions, helping maintain price stability even during volatility by actively managing supply, demand, and collateral requirements.
Reserve Coin Trading
SHEN reserve coins are actively traded to manage reserves and collateral levels, helping stabilize Djed by ensuring reserves remain strong and the protocol remains capitalized during changing conditions.
Proof of Stake (PoS)
Djed relies on Cardano’s PoS mechanism, selecting validators based on staked ADA to secure the network efficiently, ensuring honest participation and enhancing stablecoin security and sustainability.
On-Chain Data Verification
Djed ensures transparency with on-chain data access, allowing users to verify prices, supply, and reserves in real-time, promoting trust and providing accurate, blockchain-based proof of stablecoin integrity.
Smart Contracts
Djed employs smart contracts to automate key processes like minting and burning, executing predefined rules without human input, ensuring efficient, reliable, and error-free operation across the protocol.
Governance Mechanism
Djed includes a governance system enabling stakeholders to propose and vote on updates, ensuring community-driven improvements and maintaining the protocol’s effectiveness and adaptability over time.
Formal Verification
Djed applies model checking and theorem proving to validate its stability mechanisms, ensuring mathematical accuracy and system correctness, strengthening trust in the protocol’s design and operation.

Project Approach & Results
Project Approach The development of Djed began with the design of a robust algorithmic stablecoin protocol focused on maintaining price stability in a volatile market. The team started by defining the core mechanism: an autonomous system that buys and sells stablecoins to regulate their price within a specified range. They selected ADA as the primary collateral and SHEN as the reserve coin to support this mechanism. An essential part of the approach was implementing over-collateralization with a reserve ratio between 400% and 800% to absorb market fluctuations and ensure stability.
Formal verification was integral to the project. The team employed bounded model checking and interactive theorem proving to rigorously validate the stability claims of the protocol. This involved exhaustive testing and formal proofs to confirm that the system operates as intended and adheres to its stability guarantees.
Project Results Djed has been successfully implemented as an advanced algorithmic stablecoin with a proven track record of stability and security. The protocol operates effectively, maintaining its target price through a sophisticated system that autonomously buys and sells stablecoins within a specified range. The use of ADA as collateral, combined with SHEN reserve coins, supports the stability of Djed by ensuring a robust backing and high reserve ratio. The over-collateralization strategy, with a reserve ratio between 400% and 800%, effectively absorbs market fluctuations and keeps the stablecoin value consistent.
The formal verification process has been a key factor in Djed’s success. Rigorous validation through bounded model checking and interactive theorem proving has confirmed the accuracy of the protocol’s stability claims.
Challenges
Ensuring Stability Amid Market Volatility
One of the primary challenges in developing Djed was maintaining price stability in the face of market volatility. The cryptocurrency market is known for its dramatic price swings, which can significantly impact the value of stablecoins. To address this, Djed implemented an over-collateralization strategy with a reserve ratio between 400% and 800%. This means that the collateral backing Djed is significantly higher than the value of the stablecoins issued, providing a buffer against market fluctuations.
Formal Verification of Stability Claims
Another significant challenge was the formal verification of the stability claims made by Djed. The protocol needed to ensure that its stability mechanisms were not only theoretically sound but also practically reliable. This involved applying formal verification techniques such as bounded model checking and interactive theorem proving. Bounded model checking exhaustively searches for counter-examples to stability claims, while interactive theorem proving builds rigorous formal proofs.
Maintaining Transparency and User Trust
Ensuring transparency and building user trust posed a third challenge for the Djed project. For a stablecoin to gain widespread acceptance, users need to have confidence in its stability and backing. Djed addressed this challenge by providing real-time access to data on prices, supply, and reserve ratios through its platform. However, maintaining transparency requires not only accurate data reporting but also clear communication of the protocol’s mechanisms and updates.
